But when Beck and his 15-year-old son met the two teens, he quickly realized that they actually intended to rob him. Police say as Beck was attempting to leave, Johnson shot him. Meanwhile, Williams stole the dirt bike.

Neighbors heard the gunshots and helped Beck's 15-year-old son Stuart try to save his father, but there was nothing they could do.

Beck died of his injuries.

"He told his dad, 'I told you not to do this,'" said Lashaunda Hopson, who was among those who tried to help the son perform CPR. "It was senseless. It was something that could have been avoided."
